Hm. How to explain this... Well Kyoko is my daughter with Toshiko. Triesta is my daughter with a woman named Raven Darkholme. Rhiannon is my daughter with Gwen. Tyler is my son with someone named Rose Tyler and Gallifrey is his twin sister, but her father is the Doctor. So they must be from further alternate universes from yours. As I said, sweetie, it's confusing.
